Providing High-Reliability Printed Circuit Boards

For a world-class manufacturer of mission-critical, high-reliability, and time-sensitive products, look no further than Anaren and it's Unicircuit, Inc. subsidiary. Located in our dedicated PCB facility in Littleton, CO, Unicircuit is a well-respected, well-known name in the complex manufacturing process of printed circuit boards.

The cornerstone of our ability to produce and deliver products that require vertical and or horizontal launch sites for RF connectors, MMIC’s, and filter’s is our proprietary approach to multi-level cavity fabrication. This is coupled with advanced manufacturing techniques utilizing laser direct imaging, YAG laser etching, precision stub length removal, and fusion bonding.

As with all aspects of the Anaren brand, our commitment to innovation continues through our dedicated PCB fabrication facility and allows for advanced products to be developed and transitioned into manufacturable, reliable products that exhibit excellent cost vs. performance characteristics.
